What is Global Positioning System (GPS)?
GPS full meaning “Global Positioning System” . This is a navigation system that is operate using a satellite radio communication system. It’s also called the global navigation satellite systems or GNSS.
Previously Navstar GPS, the system is owned by government of the United States of America and operated by the United States Space Force.
Its main function is to send the geo-location and time information to any GPS receiver around the world.
The receiver can request this information without having the user to transmit any data themselves, making it one of the most convenient tools to use as a navigation aid.
How does GPS work?
A GPS receiver has tons of different metrics and calculations that it uses to find out your position in the world.
In layman’s terms, the receiver calculates your position in four dimensions in space-time. It calculates this information using the data that it receives from multiple satellites in orbit.
To calculate time, satellites work on an exceptionally stable atomic clock synchronized with each other.
If there even is any kind of drift, the error is corrected every single minute. The GPS receivers also have their own clocks, but they are less stable and precise in the long run.
Why Should We Use GPS?
GPS is a great invention that many people use to get around the world. Without GPS, we would not have any advancements in many fields.
Here are just some of the reasons why we should employ GPS in our day to day life,
Farming: GPS is exceptionally adept at figuring out the weather and soil conditions of an area. Using advanced telemetry, you can easily figure out how to farm your plants and crops using GPS.
Finding out location: Finding out the location of something or someone was impossible back in the early days. Now it is extremely easy to find out someone’s geo-location with the help of GPS.
Tracking Vehicles: With the help of GPS, we can easily look up the location of a vehicle, be it a truck, car or motorbike. This way, vehicles are kept safe since they can be tracked using GPS like it was in the palm of your hand.
Mapping: GPS is a blessing for cartographers because they can use the satellite cameras to easily figure out any area and map it for future generations to come.
All in all, GPS is a tremendously useful tool that has many uses in our day to day life. If GPS had not been invented we would be lost on Earth. With many uses in technological, navigational, scientific etc. fields, it is one of the golden wonders of modern science.
